I think there's more to the Develop module changes than most people realize. In addition to the very powerful new highlight and shadow sliders (quite a bit different than the highlight and shadow recovery controls found in other programs), the expanded set of local adjustments is significant. What many people don't realize is that with Lightroom (or ACR), those adjustments are made against the raw data, not applied after the fact. What this means is that whereas with other programs, you might have to create multiple raw conversions from an image and then blend them as layers in Photoshop, you can do it all from Lightroom and on the original image. Having the full set of develop sliders available means you can do whatever you want to that portion of the image that you've selected for local adjustments.
BTW, release 4.1, which will include bug and performance fixes, will also include a new feature: a pretty powerful tool for removing axial chromatic aberration. You can select which specific color bands of axial CA you want to remove. Very nice for fast prime lenses.
